Abbreviations and acronyms are essential tools in academic writing. They help streamline text, reduce repetition, and improve readability. However, improper use can confuse readers and weaken the clarity of your argument.
To ensure your writing is both professional and understandable, follow these best practices for introducing, defining, and using abbreviations and acronyms correctly.
1. Define Abbreviations and Acronyms on First Use
Before using an abbreviation or acronym, always introduce the full term the first time it appears in your text, followed by the abbreviation in parentheses.
Example:
First mention: The World Health Organization (WHO) plays a key role in global health.
Later use: WHO develops international health guidelines.
Why? Readers may not be familiar with every acronym, so defining it on first use ensures clarity.
Best Practices:
✔ Always spell out the full term before using the abbreviation.
✔ Use parentheses for the abbreviation immediately after the full term.
✔ Once introduced, use the abbreviation consistently throughout the paper.
2. Avoid Overusing Abbreviations
While abbreviations can make writing more concise, overusing them can make text harder to read—especially if the document contains multiple acronyms.
Example of Overuse:
The American Psychological Association (APA) recommends authors follow APA guidelines. APA ensures that APA citations meet APA standards.
Better Version:
The American Psychological Association (APA) provides writing guidelines. Authors should follow APA standards for citations.
Why? Repeating an acronym too often makes text cluttered and less readable.
Best Practices:
✔ Use abbreviations only when necessary.
✔ Avoid abbreviating terms that appear only once.
✔ If an abbreviation appears infrequently, consider spelling it out each time.
3. Use Standard, Recognized Abbreviations
Some abbreviations, such as “NASA” or “UN,” are widely recognized and do not require explanation. However, more specialized terms must be introduced properly.
Examples of Commonly Recognized Abbreviations:
• NASA (National Aeronautics and Space Administration)
• FBI (Federal Bureau of Investigation)
• UN (United Nations)
Best Practices:
✔ If an abbreviation is well-known, you may omit the definition.
✔ If unsure, define the abbreviation at first mention.
✔ Always check the guidelines of your academic field or journal.
4. Pluralizing Abbreviations and Acronyms Correctly
Pluralizing abbreviations follows standard grammar rules, but many writers make mistakes.
Correct Plural Forms:
• One PhD, two PhDs (no apostrophe)
• One RCT (randomized controlled trial), three RCTs
• One ATM, two ATMs
Incorrect Forms:
• ❌ PhD’s (incorrect apostrophe use)
• ❌ RCT’s
• ❌ ATM’s
Why? Apostrophes should not be used to make abbreviations plural. Apostrophes indicate possession (e.g., the PhD’s dissertation).
Best Practices:
✔ Simply add an -s to make abbreviations plural.
✔ Do not use an apostrophe unless showing possession.
5. Be Careful with Latin Abbreviations (e.g., i.e., etc.)
Latin abbreviations like e.g. (for example), i.e. (that is), and etc. (and so on) are commonly used in academic writing, but they must be used correctly.
Examples:
• e.g. (exempli gratia) → Use when providing examples.
• Many universities offer writing resources (e.g., tutoring centers, online guides).
• i.e. (id est) → Use when clarifying or restating.
• The study focused on renewable energy sources (i.e., wind and solar power).
• etc. (et cetera) → Use when listing additional items of the same kind.
• The research examined grammar, punctuation, sentence structure, etc.
Best Practices:
✔ Use e.g. for examples and i.e. for clarifications.
✔ Use etc. only when listing similar items.
✔ Do not use etc. at the end of a list that starts with e.g.
6. Maintain Readability When Using Abbreviations
Too many abbreviations can make text difficult to read, even if they are defined.
Hard-to-Read Example:
The United Nations Development Programme (UNDP) and the International Monetary Fund (IMF) partnered with the World Bank (WB) to provide financial support. The UNDP, IMF, and WB approved funding for developing nations.
Improved Version:
The United Nations Development Programme (UNDP), the International Monetary Fund (IMF), and the World Bank approved funding for developing nations.
Why? Reducing repeated acronyms improves readability.
Best Practices:
✔ Avoid using multiple abbreviations in a single sentence.
✔ If too many abbreviations are making text hard to read, spell out terms occasionally.
7. Follow Style Guide Rules for Abbreviations
Different academic styles have specific rules for abbreviations.
• APA (American Psychological Association): Requires that abbreviations be introduced on first use and used consistently thereafter.
• MLA (Modern Language Association): Generally discourages abbreviations except for well-known organizations.
• Chicago Manual of Style: Encourages clarity and suggests limiting abbreviations when possible.
Best Practices:
✔ Always check your required style guide.
✔ Be consistent—do not switch between abbreviations and full terms randomly.
✔ If in doubt, spell it out.
Conclusion
Using abbreviations and acronyms correctly can improve readability and conciseness in academic writing. However, improper usage can lead to confusion and inconsistency.

✅ Define abbreviations and acronyms on first use
